BACKGROUND:LncRNA-TNFRSF13C,an important factor in B cell development and function,is expressed in periodontal tissues of patients with periodontitis,but the specific mechanism is still unclear. OBJECTIVE:To investigate the mechanism of lncRNA-TNFRSF13C regulating miR-1246 on hypoxia-inducible factor 1α in periodontal cells. METHODS:Human periodontal ligament cells(hPDLCs)were treated with lipopolysaccharide and divided into group A(hPDLCs cell lines without transfection),group B(hPDLCs cell lines transfected with TNFRSF13C NC-siRNA),group C(hPDLCs cell lines transfected with TNFRSF13C-siRNA),group D(hPDLCs cell line transfected with miR-1246 mimics),group E(hPDLCs cell line transfected with miR-1246 siRNA),group F(hPDLCs cell line transfected with TNFRSF13C-siRNA+miR-1246 mimics),and group G(hPDLCs cell line transfected with TNFRSF13C-siRNA+miR-1246 siRNA).The relative expression of lncRNA-TNFRSF13C and miR-1246 in each group was detected by qRT-PCR.Cell counting kit-8 assay was used to detect cell viability.Apoptosis was detected by flow cytometry.Expression of hypoxia-inducible factor 1α and vascular endothelial growth factor proteins was detected by western blot.The correlation between lncRNA-TNFRSF13C and miR-1246 was analyzed by Pearson,and the targeting relationship was analyzed by dual-luciferase reporter assay. RESULTS AND CONCLUSION:There was no significant difference in human periodontal ligament cell activity,apoptosis rate and protein indexes between groups A and B(P>0.05).Compared with group B,hPDLCS cell activity in group C was increased,and apoptosis rate and the expression of hypoxia-inducible factor 1α and vascular endothelial growth factor proteins were decreased(P<0.05).Compared with group C,hPDLCS cell activity in group D was decreased,and apoptosis rate and the expression of hypoxia-inducible factor 1α and vascular endothelial growth factor proteins were increased(P<0.05).Compared with group D,the cell activity of group E was increased(P<0.05).The cell activity in group F was lower than that in group E,and the apoptosis rate was reduced in both groups E and F(P<0.05).Compared with group F,the cell activity of group G was increased,and the apoptosis rate and the expression of hypoxia-inducible factor 1α and vascular endothelial growth factor were decreased(P<0.05).LncRNA-TNFRSF13C was positively correlated with miR-1246(P<0.05).Compared with the TNFRSF13C-siRNA group,the fluorescence activity of miR-1246-wt in the TNFRSF13C-NC group was reduced(P>0.05);compared with the miR-1246-NC group,the fluorescence activities of hypoxia-inducible factor 1α-wt and vascular endothelial growth factor-wt in the miR-1246 mimics group were increased(P<0.05).To conclude,down-regulation of lncRNA-TNFRSF13C can promote the activity of periodontal cells treated with lipopolysaccharide,reduce apoptosis,and inhibit hypoxia-inducible factor 1α and vascular endothelial growth factor.The mechanism is related to the regulation of miR-1246 activity.

Objective To explore the effectiveness of"near peer learning"(NPL)in the electromyo-graphy(EMG)teaching module for neurology residents.Methods The Department of Neurology,Peking Union Medical College Hospital implemented an NPL instructional design for a course on EMG for residents from November 2020 to March 2024.This teaching session was held annually,in which senior residents in-structed juniors who were 1 or 2 years earlier in their training.The residents participated in the pre-course/post-course tests and completed a feedback survey at the end of the session.This evaluation method was used to un-derstand the effectiveness of the NPL intervention in EMG teaching.Results Over four years,a total of 83 residents participated.Among them,there were 24 postdoctoral students,52 postgraduates and 7 junior resi-dents.The results showed that the post-course test scores were significantly improved compared with pre-course test scores(74.33±2.43 vs.70.11±2.49,P=0.005),with the most remarkable improvements seen for"tu-tees"(73.84±20.53 vs.70.29±21.46,P=0.020),postgraduates(74.04±22.51 vs.68.97±21.40,P=0.009),first-year residents(70.19±4.02 vs.63.59±3.59,P=0.040)and first-time participating resi-dents(65.23±3.24 vs.60.97±3.21,P=0.030).The post-program feedback showed that both tutors and tu-tees thought highly of NPL,believing that it enabled them to gain knowledge and helped them to improve teaching skills.Conclusions The NPL intervention is suitable for the teaching of EMG,because of its contri-bution to knowledge acquisition and basic clinical skills improvement.The NPL is worth replicating in other teaching and learning programs.

This paper summarizes Professor WANG Xiuxia's clinical experience in treating hyperprolactinemia using the liver soothing therapy. Professor WANG identifies liver qi stagnation and rebellious chong qi （冲气） as the core pathomechanisms of hyperprolactinemia. Furthermore， liver qi stagnation may transform into fire or lead to pathological changes such as spleen deficiency with phlegm obstruction or kidney deficiency with essence depletion. The treatment strategy centers on soothing the liver， with a modified version of Qinggan Jieyu Decoction （清肝解郁汤） as the base formula. Depending on different syndrome patterns such as liver stagnation transforming into fire， liver stagnation with spleen deficiency， or liver stagnation with kidney deficiency， heat clearing， spleen strengthening， or kidney tonifying herbs are added accordingly. In addition， three paired herb combinations are commonly used for symptom specific treatment， Danggui （Angelica sinensis） with Chuanxiong （Ligusticum chuanxiong）， Zelan （Lycopus lucidus） with Yimucao （Leonurus japonicus） ， and Jiegeng （Platycodon grandiflorus） with Zisu （Perilla frutescens）.

Sterilization is one of the key links in the production of traditional Chinese medicine,and it is also an important factor to ensure the safety,effectiveness and quality control of traditional Chinese medicine.Traditional sterilization techniques such as moist heat sterilization are limited in many cases due to their inherent shortcomings.In contrast,irradiation sterilization has attracted more and more attention due to its advantages of fast,efficient,strong sterilization and low cost.However,the chemical composition of traditional Chinese medicine is complex,due to the radioactivity and strong penetration of irradiation,after a certain dose of irradiation,its chemical composition and pharmacological activity may change.At present,there is still a lack of systematic research on the changes of chemical composition,effectiveness and safety of traditional Chinese medicine after irradiation sterilization.Based on the research status of 60Co-γ ray and electron beam irradiation sterilization in the sterilization of traditional Chinese medicine in recent years,this paper reviews the effects of irradiation on the effectiveness of traditional Chinese medicine,the detection methods of irradiation and the safety evaluation,in order to provide some reference for the subsequent application of irradiation sterilization of traditional Chinese medicine.

The traditional acute care model, focused on disease diagnosis and treatment, is struggling to meet the complex needs of elderly patients at the end of life, encompassing physical, psychological, social, and spiritual aspects.Hospice care, designed to enhance the quality of life and death for patients in this stage, offers a suitable service model for the elderly.Hospice care for elderly patients at the end of life should be centered around the patient, honoring their preferences, and delivering comprehensive care that addresses their overall well-being.The lack of knowledge about hospice care among healthcare professionals often hinders its implementation, negatively impacting the quality of life for these patients.This article aims to outline the key features of hospice care services for elderly patients at the end of life, serving as a valuable reference for clinical practice.

To improve the understanding of the special imaging features of pulmonary cryptococcosis in immunocompetent individuals and reduce misdiagnosis and missed diagnosis through the analysis of rare clinical cases and literature review. We reported a case of normal immunocompetent pulmonary cryptococcosis with pulmonary hypertension and COVID-19 weak positive nucleic acid during convalescence, CT scan of the lungs revealed rare features similar to pulmonary interstitial changes. Literature was reviewed to further discuss pulmonary cryptococcosis's clinical symptoms, imaging manifestations, diagnosis, and treatment outcome. The patient with severe aortic stenosis needed to be treated by surgery as soon as possible. Secondary pulmonary infection, subacute onset, and clinical manifestations were nonspecific, and empirical anti-infection treatment at the beginning of the disease was not effective. The timely revision of the examination confirmed that the predominant causative agent was Cryptococcus neoformans, and prompt administration of antifungal treatment facilitated surgical intervention and yielded favorable therapeutic outcomes. Literature review revealed that it is rare for pulmonary cryptococcosis in immunocompetent patients to present with pulmonary interstitial changes on CT findings.Pulmonary cryptococcosis presents with non-specific clinical symptoms and diverse imaging features, making it prone to mixed infection and requiring high vigilance. In this case, the immunocompetent patient's pulmonary CT findings exhibited changes resembling those in immunodeficient patients with pulmonary cryptococcosis. The underlying pathogenic mechanism needs to be further explored.
